I guess we are all a little too eager with these kits. Have you already ordered parts for the 4cap kits? If not, let's figure out the price difference and see if people would be will to pay the difference, then we can all get the new boarsa and kits. Hopefully the price difference won't be too great. One alternative would be to use the new boards and only use 4 caps. Who knows.

Brian, will the price of the new boards be higher? I think I already paid for the boards too, but I actually am starting to get confused about what I have paid for (building 4 amps at the same time is most confusing).

The pricing for the boards will not change, regardless of which ps board design is chosen. Jason hasn't ordered any parts yet, and we will work something out.

What are the advantages to the new caps your board now accomodates? Larger Capacitance?

Thanks,

The older caps still work. The newer caps offer higher capacitance.

The only drawback to the new caps is the size. The Panasonic TS-UP caps are offered in a lower profile, which wouldn't really be an advantage to the Aleph designs, since the heatsinks will have to be relatively large anyway, making the chassis profile relatively tall.

On a side note, I ordered the pcbs today, 3 oz copper, blue soldermask, 0.093" fr4, with a 2 week leadtime. Hopefully they will ship sooner (AC has been good with this and often ships a few days early). This means that in 2 weeks, I will have the boards in my hands.

I went with the larger 6 capacitor power supply board, and will post pictures/info tonight on the final layout.

Im helping my friend build an aleph 5 with these boards. this question was asked before, not sure if it got answered. By setting the board up for aleph 30, is it just a matter of raising the rail voltage to achieve aleph 5 status. looking at a30, the schematic for the input stage (esp around diff pair)is slightly different, everything else seems to be the same, except for a few different values, a5 with higher input impedance

is it just a matter of raising the rail voltage to achieve aleph 5 status.

Not only that. Hit up passlabs and compare the schematics for A30 and the A5. Check the amount of Mosfets on the output/CCS, the source resistor values and the railvoltage. Also the size of toroid/supplycaps and so on. Propably some more issues also. Its all in the schematics
